Definitions

  • the present invention relates to a method for refueling with cryogenic liquid, in particular with liquefied natural gas, as well as a device for implementing such a method.
  • Some vehicles most often trucks but also for example ships, use liquefied natural gas as fuel. Refueling stations should be provided for these vehicles in order to be able to "refuel” as is conventionally done with a vehicle running on gasoline or diesel.
  • WO-2011/152965 is considered here as the document of the prior art closest to the present invention. It presents a method and apparatus for delivering LNG for supplying gas from a storage tank at specified temperature and pressure conditions.
  • the method described provides for steps of pressurizing an LNG enclosure (called conditioning tank in this document) at a first pressure, then conveying the LNG at a second pressure greater than the first pressure to a condenser which is in a heat transmission relationship with the enclosure, and finally LNG extraction from the condenser.
  • the problem at the origin of the present invention stems from the fact that all vehicles do not require the same pressure and the same temperature for refueling with LNG.
  • a device described in the document WO-2011/152965 it is possible to vary the refueling pressure (and temperature) but to switch from one pressure (and its associated temperature) to another, the time required can be relatively long, of the order of an hour or more .
